Hello,I am currently working on interfacing an OV7670 camera with an STM32F429 using DCMI + DMA, and displaying the captured image on an ILI9341 LCD (SPI interface).I have successfully confirmed that the LCD itself works correctly (for example, filling the screen with a solid red color).However, no camera image is displayed, so I suspect there may be an issue with the camera operation or the DCMI configuration.I am using the following repository as a reference:https://github.com/PHANzgz/STM32-H7-camera-interface-and-displaySince this project is originally for STM32H7, I have modified the configuration as much as possible to make it suitable for STM32F429.At this point, I would like to ask whether there are any STM32F4-specific considerations, missing settings, or common pitfalls when using OV7670 with DCMI + DMA.Any advice or working references for OV7670 + STM32F429 would be greatly appreciated.Ths is my code./* USER CODE BEGIN Header */ /** ******************************************

Hi all,I used STM32H7S78-DK and everything was fine: I was able to load and flash the "HVAC Iot Demo" from TouchGFX Designer at the first time and develop my application using STM32CubeIDE.Then I bought an STM32N6570-DK and did the same procedure as before, but I was not able to flash that demo.I can successfully generate the code inside the TouchGFX Designer (version 4.26.0) but, when I push the button "Program and run target", I get this kind of error: Erasing memory corresponding to segment 0:Erasing external memory sector 0Error: failed to erase memoryError: failed to erase memoryc:/TouchGFXProjects/STM32N6570DK/IotDemo/MyApplication/gcc/include/flash_sections_int_ext.mk:18: recipe for target '_fsblflash_' failedmake[2]: *** [_fsblflash_] Error 1makefile_fsbl:45: recipe for target 'flash' failedmake[1]: *** [flash] Error 2../../gcc/Makefile:8: recipe for target 'flash' failedmake: *** [flash] Error 2FailedFailed Can anyone please help me?

Hi !We're testing with the eval-boards NUCLEO-H7S3L8 + X-NUCLEO-67W61M1.The software is the CLI project of the NUCLEO-H7S3L8.At the bottom of this post you will find infos to the software versions.There we're having an issue when we try to connect to an WiFi AP and the password includes a comma (',').It looks the ST67W6X_Network_Driver is encoding and sending the AT-command correctly, but the NCP (ST67W611M1) response with ERROR.So it seems to us it's an issue of the NCP firmware.Via Shell/CLI we initiate the connection to the WiFI AP via the command wifi_sta_connect.When we set the password at the AP to "pw123456" we can connect to the AP.When we set the password at the AP to "pw123,56" we can not connect to the AP.For debugging we followed the code in the ST67W6X_Network_Driver till function W61_AT_Common_SetExecute(..).There the AT-command is sent and the response is received.If the password is not including a comma, it is connecting to the WiFi AP successfully.The communication of

Hello everyone,I'm writting today because I have some questions about the memory assignment of the flash on dual core devices such as stm32h745 mcu.I'm trying to assign a direction for the boot program, imagine 20k from "0x08000000". Afterwards I wan to assign 1.5mb for the cm7 and the rest for the cm4.As I understand, by default the flash is separated in 2 banks, first bank for the cm7 and second one for the cm4.I wanted to know if it was possible to use the first bank and half of the second for the cm7, and the rest for the cm4.If so, how I should proceed to achieve that? Because I managed to set the beginning of cm4 on another memory direction by setting the FLASH_BANK2_BASE define, but I don't feel like this is the best approach.Any ideas would be greatly appreciated.Best regards,RPC    

Hello,Right now I am using 2 STM32WBA55G-DK1, one as PBP_Source and other is TMAP_Peripheral. The source consists of 2 BIS channels and in TMAP, I have included language selection option to include the subgroup or channel selection. And its working fine. But if I select Unicast option and pair with S24 mobile, only first channel or subgroup I can select, not the 2nd one. May I know whats the reason and how to overcome from this. Thank you

Hello,I am trying to start a new project on a STM8s003K3 discovery kit, i have downloaded and installed STVD without a problem but I can't download Cosmic C Compiler. The download link in the Cosmic site is not working, I have tried anything I can think of (changing DNS settings, resetting IP, checking host file) to fix timeout error thinking the problem was on my end but I can't download it on another pc connected to another WiFi either so I think it is the download link which is broken. Any ideas what might be the issue? If this is unfixable there any other opensource compiler for stm8s?

Hi,i have a bit of situation here.I wanted to try a zigbee example from cube mx (On/off ED).So i first flashed the FUS v2.2.0 on the device.But now it turns out that i can not flash the desired FW anymore : stm32wb5x_Zigbee_FFD_fw.bin.It only errors :(I have the feeling that this FW is not working with FUS 2.2?If so - I am right that i can not downgrade FUS anymore once it is updated? This basically would mean i wasted hundreds of EURs for those dev boards. 

Hello everyone,I am using the X-NUCLEO-NFC10A1 NFC reader with an NXP MCU.I am able to successfully detect a MIFARE Classic 4K card using this reader.However, when I try to authenticate a sector for read/write access, I encounter an issue.I am sending the authentication command using the sequence:[ AUTH_CMD + BLOCK_ADDRESS ]After sending this command, I get a timeout error.I tried increasing the timeout value, but the issue still persists.When I manually append the CRC to the authentication command and transmit it, the reader returns a framing error.Could someone please confirm:    Is this the correct way to perform MIFARE Classic 4K authentication using the ST25R200?    If yes, what could be the reason for the timeout or framing error?If anyone has reference code, application notes, or examples related to MIFARE Classic authentication with ST25R200, please share.Thank you in advance for your help.

Hi all, I've recently been working on a Nucleo H723ZG with a working implementation that allows for ADC reading over DMA. I've got a Timer event that triggers it at 20kHz and it was reading and processing multiple ADCs. I've shifted to using a custom developed board with a surface mounted STMH733VGT6. I've configured the ADCs and timers to what I believe is the exact same as before. I have verified that there is nothing wrong with the ADC circuitry by initially setting them up using poll for conversion, I was able to get valuable data out of the board doing this.When I went to setup the ADCs to use DMA however I started to have issues, I believe that theHAL_ADC_ConvCpltCallback isn't being called but I am not sure why, I set a break point in there which is never reached. Below I have copied in my TIM1 init function as well as my ADC1 init function in hopes that it may help someone assist me with my issue.  Really appreciate you taking the time to read this and assis

I'm using STM32CubeIDE Version 2.0.0 and would like to get the size of all the object files in my build. I know I can do this in Project Settings->C/C++ Build->Settings->Build Steps->Post-build steps->commands using arm-non-eabi-size, but what is the variable that expands to the names of the object files, and how do I use it?

Hi. Unfortunately, after several days of struggling with USBX, I'm forced to ask for your help. I'm using custom boards with the STM32h503RB and STM32h563VI. I tested the old library according to forum guides – no response when connected to a PC. The closest I've gotten is following the guide for USBX C0. Windows recognizes the CDC device and assigns a COM port, but there's no response when attempting to open the port.USBX standalone,interrupt enabled, Clock 48MHz, CRS enabled, mempoll size 8*1024, stack size 6*1024https://www.youtube.com/watch?v=43gcc2dGnxQ int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ /* USER CODE END SysInit */ /* Initi

Strange things are happening: I'm running STM32CubeIDE under macOS 15.7.2 (I must admit it is OCLP Sequoia). A couple of minutes ago I was able to open .ioc files in my project - not sure whether that was before the upgrade. Nowthe .ioc are upper strip blue, lower half green. What does that mean? When I invoke the .ioc by double click, it switches over to my Windows VM (Parallels) and fires up CubeMX there (a very old version). When the VM is not running, STM32CubeIDE does nothing. The .ioc is not opened like I was used to before. I'm now updating. I'm puzzled.

Hi everyone!Could someone help me to understand a problem with STM32G070.We have deployed approx. 50-60 devices with stm32g070 MCU that saves some parameters in FLASH every 24 hours. I know that according to datasheet FLASH memory endurance for this MCU is 1000 cycles. So, in theory, this MCU can work normally 2.7 years. It is also worth to mention that this period is defined for temperature range of -40 to +85°C. Recently, we had a relative cold weather with a temperature ranging from 0 to -10°C. This is far from -40°C that we see in datasheet. However, we had 5-6 devices that have corrupted parameters area (last page from 128K FLASH memory).I was able to reproduce this situation in the office. So I wanted to ask you guys if you had such a strange behavior with this MCU or another one. I need to mention also that this board is coated with special waterproof-coating.Erase and program functions looks like that:HAL_FLASH_Unlock(); uint32_t defectPages; FLASH_EraseInitTypeDef EraseInitSt
